Example Input: Passage: By the 1920s, SCGX was doubling annually and had emerged as the "fastest growing grain market in the world"; transacting 22 million bushels in 1928 (valued at $336 million in 2018), resulting from its location in the heart of the Corn Belt and self-imposed standards before the Grain Standards Act of 1916 including species admittance and non-mixing. However, its growth was limited by shipping rates. With the trucking industry and Interstate Highway System not yet developed, SCGX was constrained by monopolized railroad rates, primarily by the Great Northern Railway. Exhausting their bargaining power with the Interstate Commerce Commission, SCGX President Charles C. Flanley directed future lobbying efforts to unlocking barge navigation of the Missouri River. His initiative was stalled throughout the 1930s by the Great Depression and Dust Bowl. In 1938, a renewed thirteen year campaign led by Secretary William Henry Marriott finally opened commercial navigation of the Missouri River and helped establish the Missouri River Basin Project, which included development of the Gavins Point Dam. The alternate transportation succeeded in breaking the railroad's monopoly. By the 1970s, SCGX was among the largest exchanges in the world; transacting over 100 million bushels annually (valued at $1 billion as of 2018).

Example Input: Passage: The Bagration family's genealogy traces back at least to the medieval era in its male line and hundreds of years further back as rulers in the female line. Leonida's grandfather, Prince Alexander Bagration of Mukhrani, was born in 1853 in Georgia's historical capital Tbilisi, then part of the Russian Empire, and was killed by Bolsheviks at Pyatigorsk in 1918 during the Russian revolution. Fearing for their lives, the family took refuge in Constantinople, then spent eight months in Germany before returning to Tbilisi, now capital of the Georgian Soviet Socialist Republic, to re-claim a portion of property which, as émigrés they risked losing to total confiscation. Although the family made repairs to their home and Leonida would recall her grandfather's insistence that they continue to dine formally on silver plate to retain their sense of propriety, they were eventually deprived of all but two rooms of their old palace and subjected to harassment. Thanks to the intervention of Maxim Gorky, who had enjoyed the patronage of the Bagrations, in 1931 they once again fled the Soviet Union, going into exile in Spain. The family moved to France, where Leonida's grandmother and relations had already settled.
